feat: initial bluetooth support (#9)

* Enable Bluetooth LE radio support
* Build our own bccmd which we need to setup/enable this BT chipset sadly
* Use our own tool we build to interface with the ubnt eeprom, so we can not rely on their custom kernel module
* Also fix HDDs not spinning down on shutdown, doing something similar to how unifi does it but a tad more generic.
